The Fall #22 states that the Future Luci & Imps we’ve seen are the Paradox that will soon be erased. They’ve been wandering all across time doing heavens know what, and they have an idea of how to resolve the problem. They just have an idea (ie remove Luci from access to both sides. This would of course ensure she can’t bring about the end of times.) They never guaranteed it would work, just that they had an idea.

That’s all we know right now. This could be a vision, this could a reality that Luci has to unwrite. We’re lacking context on the situation to know anything and that leaves us confused. Like I said, it was a heavy whiplash, and that’s what’s causing so many questions and concerns.
